SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 587,915, dated August 10, 1897. Application filed October 16, 1896. Serial No. 609,075. (No model.)

T0 all witam it may concern:

Be it known that 1, GEORGE WASHINGTON BECK, a citizen of the Unit-ed States, resid-' iug at Hamilton, in the county of Hamilton and State of Texas, have invented a new and useful Sash-Holder, of which the following is a specification.

This invention relates to sash-holders; and the object in view is to provide a simple, cheap, and durable device of the nature referred to which will operate automatically when the window-sash is raised or lowered to hold the same wherever it is left without the use of a bolt or other similar positive fastening device.

To the ends above noted the invention consists in an improved sash-fastener embodying novel features and details of construction, all as hereinafter particularly set forth, illustrated in the drawings, vand incorporated in the claim.

In the accompanying drawings, Figure 1- is a perspective view of a window-frame, &c., broken away to show the application of the perforated strip forming the rack-plate. Fig. 2 is a detail perspective view of the rackplate. Fig. '3 is a detail Vertical section showing the operation of the improved holder. Fig. 4: is a detail perspective view of the members of the sash-holder.

Similar numerals of reference designate corresponding parts in the several figures of the drawin'gs.

The improved sash-holder contemplated in this invention consists, essentially, of a spring 1 and a toothed roller 2. The spring 1 is rigidly secured at one endto the onter edge of the side rail of a sash, and the free end of the spring is defiected laterally, so as to project normally outside of the edge of the sash, and the extremity of the spring is slotted, as indicated at 3, and the divided portions of such extremitynpon each side of said slot are rolled in circnlar formJ as indicated at 4, to form eyes or b'earings for the roller.

The roller 2 is provided with fiat edges or sides and is made substantially square, as shown in Fig. 4:. The roller is also provided at each of its four Corners with a tooth 5, for a pnrpose that will hereinafter appear, and upon each side the roller has laterally and oppositely projecting trunnions 6, which enter and have their bearing in the eyes 4 of the spring 1.

The side rail of the sash is mortised out, as indicated at '7, to allow of the necessary vibration of the free end of the spring 1, and a rack-plate 8 is secu red to the window-frame immediately opposite to the side bar of the sash. This rack-plate consists of a metal strip, which is provided with a longitudinal series of perforations 9, in which the teeth of the roller 2 engage as the sash is raised or lowered, and said plate extends vertically and practically the entire height of the sash.

The arrangement above described is duplicated at each side of the sash, and Vwhile the sash-holders are applied to the lower sash near its bottom edge the holders of the upper sash are applied thereto near the top edge.

By reason of the particular shape of the roller' 2 as the sash is moved up or down said roller will vibrate the spring l and the spring will act by its tension to force the roller into engagement with the rack-plate. While the sash is moving, at least one of the teeth pmust engage the rack-plate,vbut when the sash is. stopped one of the fiat sides or edges of the roller 2 will bear firmly againstvthe rackplate 8, while two of the teeth 5 will enter adjacent perforations in the' plate 8. The sash will thus be firmly held at the point where it is left without the use of a bolt or similar positive fastening device, and as the Wheels 2 and the rack-plates 8 are exact duplicates of each other on each side of each sash the sashes must'necessarily travel up and down equally at bothsides, so that they cannot bind or become wedged'between the jambs of the window-frame. p

It will be understood that the sash-holder above describedis snsceptible of changes in the form, proportion, and minor details of construction, which may accordingly be resorted to without departing from the spirit or sacrificing any of the advantages of this invention. w

Having thus described the invention, what is claimed as neW is-- A sash-holder consisting of a leaf-spring adapted to be secured at one end to the sash and having journals in its free end, a roller IOO Io held in its adjusted position Without the use of a bolt 01' other similar positive fastening device, substantally as desoribed.

In testinlony that I claim the foregoing as inyovn I have hei'eto affixed my signature in the presence of two Witnesses.

GEORGE WASHINGTON BECK.
